布尔列始终在SQL查询中返回false

Question

NET MVC核心2.2和Mssql.I写了一个存储过程，可以正常工作。结果：

但是，每当我运行我的应用程序时，所有stockPermit列均返回false。

控制器

if (!String.IsNullOrEmpty(searchString))
{
    searchString = Methods.RemoveTurkish(searchString);
    bayiVM.JoinedTable = await _adb.CariUserJoin.FromSql("EXECUTE CariListeAra {0}", searchString).ToListAsync();
}
else
{
    bayiVM.JoinedTable = await _adb.CariUserJoin.FromSql("EXECUTE CariListeGetir").ToListAsync();
}

var count = bayiVM.JoinedTable.Count;
bayiVM.JoinedTable = bayiVM.JoinedTable.Skip((productPage - 1) * PageSize).Take(PageSize).ToList();

bayiVM.PagingInfo = new PagingInfo
{
    CurrentPage = productPage,
    ItemsPerPage = PageSize,
    TotalItems = count,
    urlParam = param.ToString()
};

return View(bayiVM);

调试结果：

什么会导致此问题。感谢您的帮助。

存储过程1

ALTER PROCEDURE [dbo].[CariListeGetir]
AS
BEGIN

    SELECT [CARI_KOD], [CARI_ISIM], [LockoutEnd],[PlaKodu], [StockPermit] FROM YESLAS2018.dbo.TBLCASABIT
    left join b2byeslasDb.dbo.AspNetUsers on TBLCASABIT.CARI_KOD=AspNetUsers.UserName
END

存储过程2

ALTER PROCEDURE [dbo].[CariListeAra] (@ad nvarchar(15))
AS
BEGIN

    SELECT [CARI_KOD], [CARI_ISIM], [LockoutEnd],[PlaKodu], [StockPermit] FROM YESLAS2018.dbo.TBLCASABIT
    left join b2byeslasDb.dbo.AspNetUsers on TBLCASABIT.CARI_KOD=AspNetUsers.UserName
    where CARI_KOD like '%'+@ad+'%' or CARI_ISIM like '%'+@ad+'%'

END

我的视图模型

public class BayiVewModel
    {
        public List<CariUserJoin> JoinedTable { get; set; }
        public PagingInfo PagingInfo { get; set; }
    }

CariUserJoin：

public class CariUserJoin
    {
        [Key]
        public string CARI_KOD { get; set; }
        public string CARI_ISIM { get; set; }
        public DateTimeOffset? LockoutEnd { get; set; }
        public string PlaKodu { get; set; }
        public bool StockPermit { get;set}

    }

PS：我使用了LEFT JOIN。我的意思是左表有4500行，右表有30行。

请使用：

public bool? StockPermit { get; set; }

需要

set;以便可以实际设置该属性。需要?使其可为空。
